Iron-based flow batteries have emerged as a promising technology for large-scale energy storage, particularly in integrating renewable energy sources into the electrical grid. 6,7 These iron-based redox flow batteries present an attractive alternative to conventional energy storage solutions due to their low cost, material abundance, and environmental compatibility. 5,6 The widespread availability of iron, which can be obtained for less than $ 0.10 per kilogram, and the ability to leverage waste products like iron sulfate, contribute to the economic viability of iron-based redox flow batteries for large-scale energy storage applications. 5,6,8 The operational mechanism of all-iron redox flow batteries differs significantly from that of conventional all-liquid redox flow batteries due to the presence of a solid–liquid phase transition.
